How is video calling?
Often people know how to do video calling but they do not know how it is video calling? So let’s get more information about this.
Video calling is also technically called Voice over Internet Protocol (VoIP). This is a very popular standard through the web of voice and video calling. We all have different platforms for making voice and video calls such as WhatsApp, Skype, Messenger, Facebook Let’s use
Basically, both voice and video call depends on how the media can be streamed between two clients that are connected with each other. So there must be something that can do this task of media streaming from one client to another.
To understand this media streaming, we need Webrtc Need to know about
What is WebRTC?
WebRTC is a free, open project that provides real-time communications (RTC) capabilities to browsers and mobile applications through simple APIs. These WebRTC components are customized according to the requirement to perform their work properly.
But with this we have to do more things with WebRTC so that we can implement it correctly.
Those other things are
- STUN Server
- TURN Server
What is signaling?
They are setup before a call is made between two clients, both clients must be confirmed with each other for which they have to do some tasks such as sending key data, messages, about metadata media. All these functions are done in signaling.
We can use WebSocket to perform signaling.
It only shows that both clients are ready for a call to connect with each other.
Peer to Peer Connection
After signaling, we have to connect both clients peer to peer. And to connect, we must have public IP address for both clients.
So to get a public IP address, we have to use STUN Server.
The STUN Server is used to obtain a public IP address.
Why do we need a Public IP Address?
One Public IP Address That IP address is called globally unique throughout the Internet. Only one device must have that public IP address. Meaning that the same public IP address cannot be in more than one device.
There only Private IP Address That IP address is called that is not globally unique and can be simultaneously connected to more than one different device. A private IP address is never directly connected to the Internet. Devices that have a private IP address are unique in their own unique IP space (eg different companies or domains).
like NAT(Network Address Translation) Provides the local IP address of a device that cannot be used publicly to connect peer to peer. And for WebRTC, we require a special public IP address. Which we get from STUN Server.
If everything is done properly, then we get public IP addresses of both clients, and we can connect both these clients through WebRTC and start the call. WebRTC to all media streaming handle Is able to do.
Now comes the problem that this real world connectivity is not as ideal as it should be.
In such case, we do not get public IP address of both clients. Because of which we cannot connect peer to peer. This is why we need a TURN Server.
What is TURN Server?
The TURN Server is used to connect both clients if peer to peer fails to function like a mediator. Basically, it takes data from one client and sends it to another client. Therefore, its function is to relay to the media.
In this way, two clients start interacting with each other.
Other small data which is not related to the media, such as a client cuts the call, any setting changes, messages etc. that are used in the signaling process.
Often people get the question that why WebRTC do not signaling?
The answer is: To avoid redundancy and to maximize compatibility with other established technologies. Signaling methods and protocols are not specified in the WebRTC Standards.
WebRTC is optimized for media only. And this is how voice and video call works.
Is my video call safe or not?
By the way, it is more difficult to give a simple answer to whether Video Calls is safe because the answer is yes and no. Let us understand both things in some detail. Three reasons why Video Calls are safe?
1. It probably does not contain any intermediary
Most video chats take place in a direct machine-to-machine connection. To deliver video stream efficiently, data is sent directly from one computer to another. There is no server or service in middle processing to capture the video stream.
2 . Most chats are encrypted
You are using any type of service, all the data that transmit in it encrypted Occur. Even if someone intercepts that data such as your ISP, it is not so easy to decipher it.
3. Maybe you are not that much interesting
I want to disappoint you by saying this, but it is true that you and we are not so much interesting people who investigate other people and intercept our video. If seen, there are other people on whom they can do this and not on us.
Some Common Causes Why Video Calls Are Not Safe?
Maybe video calls may not be too safe, because if the other person who is on the receiving end, if he is using a screen recorder, then you will not know anything about it. This work is often done to blackmail.
Nobody can do anything in it because no different hacking technology is used in it, just a video recording software is used which is a normal software.
Or it could be that if there is already someone in your computer malware If he is mehud then he hacker Who he malware It has been installed, it can record all your video stream and can also blackmail you later.
What is the difference between Video Call and Voice Call?
Video calling You can hear and see each other Voice call I can only hear each other. Internet calling is required for video calling, while normal network is enough for voice calls. Video Calling uses a lot of data.
